4 Claims. 1

This invention relates to new and useful improvements and structuralrefinements in holders for sheet material, more specifically, materialsuch as insulating board panels, insulated brick siding, or the like,and the principal object of the invention is to provide a device of thecharacter herein described whereby such material in either sheet orstrip form may be firmly and securely held while it is bein marked orcut.

A further object of the invention is to provide a holder which willaccommodate strips or sheets of various sizes and with the assistance ofwhich the measuring and cutting operation may be easily and accuratelyperformed.

Another object of the invention is to provide a holder which is simplein construction and which will not easily become damaged.

An additional object of the invention is to provide a holder which maybe conveniently transported and which will readily lend itself toeconomical manufacture.

With the above more important objects in view and such other objects asmay become apparent as this specification proceeds, the inventionconsists essentially of the construction and arrangement of parts asshown in the accompanying drawings in which:

Figure 1 is a top plan view of the invention;

Figure 2 is a front View thereof;

Figure 3 is a cross sectional view, taken substantially in the plane ofthe line 33 in Figure 1;

Figure 4 is a fragmentary cross sectional detail showing one of thelocking cams used in the invention;

Figure 5 is an underside plan vie-w of the cam shown in Figure 4, butillustrating the same removed from the structure in which it is mounted;

Figure 6 is an elevational view of the device shown in Figure 5;

Figure 7 is a cross sectional View, taken substantially in the plane ofthe line Il in Figure 1;

Figure 8 is a perspective view of a gauging member used in theinvention, and

Figure 9 is a cross sectional view, taken substantially in the plane ofthe line 9-9 in Figure 1.

Like characters of reference are used to designate like parts in thespecification and throughout the several views.

Referring now to the accompanying drawings in detail, the inventionconsists of a holder designated generally by the reference character I0,the same embodying in its construction a flat platform or bed IIsupported in elevated position 2 by a pair of rails I2 which are securedto the under side of the bed, as is best shown in Figure 7 A pair ofparallel guides I3 are secured at the side edges I l of the bed ii, theinner, that is, the opposed faces of the guides being formed withlongitudinally extending grooves or channels I5.

A substantially U-shaped gauging member I6 is slidable on the bed IIbetween the guides I3, the side arms ll of the member I6 being providedwith laterally projecting rails 58 which slidably engage the channelsI5, as will be clearly apparent.

The side arms I! of the member I6 are secured to the mid-portion I 9 ofthe member in any suitable manner and a pair of braces 20 are alsoprovided to reinforce the member structure. It will be observed that bysimply sliding the member I3 between the guides I3 as indicated by thearrows 25, the distance of the member portion I9 with respect to thefront edge 22 of the bed II may be readily varied.

The member I 6 may be releasably locked in any desired position by apair of locking cams 23, each of which is rotatably positioned in arecess 24 formed in the forward end portions of the side arms II. Eachof the cams 23 may be actuated by means of a handle 25 formed integrallywith the boss 26 which is also provided with a shank 21.

As is best shown in the accompanying Figures 4 and 6, the shank 2'!includes a cylindrical portion which is rotatable in a bore 28 providedin each of the side arms I], while the cam 23 is mounted upon a squareportion 29 of the shank, where it is retained by means of a suitable nut30.

The cams 23 are disposed in alignment with the channels I 5 of theguides I3 and it will be understood that by simply actuating the handle25, the cams will be brought in frictional engagement with the groovesI5 and the member I6 will be releasably retained or locked in position.It should be added that the continuity of the rails I8 is interrupted asat 3!, so as to accommodate the cams 23, as is best shown in Figure 8.

A clamping strip 32 is attached at one end thereof to one of the guidesI3 by means of a hinge 33, while the remaining end of the strip isequipped with a tubular socket 34 accommodating a slidable locking bolt35. This locking bolt is receivable in an eye or socket 36 secured tothe remaining of the guides l3, as will be clearly apparent.

Finally, it will be observed that either one or both of the guides I3are inscribed with a grad- 3 uated scale 37, the zero line of the scalecoinciding with the front edge 22 of the bed H.

When the invention is placed in use, a strip or sheet of material 38 ispositioned on the bed H so that one edge 39 thereof contacts the gaugingmember IS. The locking cams 23 may then be loosened and the gaugingmember may be adjusted with respect to the scale 37 so that the distancebetween the forward edge 40 .of the gauging member and the edge 22 ofthe bed is equal to the length or width of the material desired.

The locking cams 23 should then be retightened and the clamping strip324Whichheretofore has been in an open position) should be lowered so asto press upon and firmly hold the material to be cut. The cuttingoperation may be undertaken by simply using the edge 22 of the bed as aguide for the cutting instrument.

The locking bolt 35 and the co-acting eye 36 serve to retain theclamping strip 32 in the closed position, as will be clearly understood.

It is believed that the advantages and use of the invention will beclearly apparent from the foregoing disclosure and accordingly, furtherdescription thereof at this point is considered unnecessary.

While in the foregoing there has been shown :and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted toiwithoutdeparting from the spirit and scope oi theinvention as claimed.

What I claim as my invention is:

1. 'A holder for sheet material, comprising in combination, a flat bed,a pair of parallel guides provided at the side edges of said bed,asubstantially U-shaped gauging member slidable in said guides,releasable means for locking said member, a material clamping striphinged at one end thereof to one of said guides, a'locking bolt rat theremaining end of said strip, and an eye onwthe remaining of said guides,said bolt being engageable with said eye.

2. The device as defined in claim 1, in which said means for lockingsaid member comprises a pair of cams provided on said member, said camsbeing frictionally engageable with said guides.

3. A holder for sheet material comprising in combination, a fiat,elevated bed, a pair of parallel guides secured at the side edges ofsaid bed, the opposed faces of said guides being formed .With a pair oflongitudinally extending channels, .a substantially U-shapedgaugingmember slidable between said guides and engaging said channels, alocking cam provided at each end of said member and adapted toreleasably engage said guides, and a clamping strip associated with said,guides, said strip being adapted to releasably retain the material onsaid bed.

4. -A-holder for sheet material comprising in combination, a flat,elevated bed, a pair of parallel guides secured at the side edges ofsaid bed, the opposed faces of said guides being formed with a pair oflongitudinally extending channels,

a' substantially U-shaped gauging-member slid- EDWARD C. BLASKE.
